Below programs illustrate the imagesetthickness() function in PHP:
Program 1:
<?php   // Create an image of given size $im = imagecreatetruecolor(400, 300); $green = imagecolorallocate($im, 0, 153, 0); $white = imagecolorallocate($im, 0xff, 0xff, 0xff);   // Set the background to be white imagefilledrectangle($im, 0, 0, 400, 300, $green);   // Set the line thickness to 5 imagesetthickness($im, 5);   // Draw the rectangle imagerectangle($im, 50, 50, 350, 250, $white);   // Output image to the browser header('Content-Type: image/png');   imagepng($im); imagedestroy($im); ?> |
Output:
Program 2:
<?php    // Create an image of given size $im = imagecreatetruecolor(400, 100); $green = imagecolorallocate($im, 0, 153, 0); $white = imagecolorallocate($im, 0xff, 0xff, 0xff);    // Set the background to be white imagefilledrectangle($im, 0, 0, 400, 300, $green);    // Set the line thickness to 15 imagesetthickness($im, 15);   // Draw the line imageline($im, 50, 50, 350, 50, $white);    // Output image to the browser header('Content-Type: image/png');    imagepng($im); imagedestroy($im); ?> |
